Hello baby1971, and welcome to the discussion forum!
In response to your first point, it seems to go both ways. I mean, the Muslims see America's military adventure into the east and fear that America wants to spread its western religion there, while here in the west there is fear of the Muslims taking over. I worked alongside a moderate Muslim last year who came to be a very good friend of mine (he was from Pakistan). I believe that many, perhaps most Muslims are like him, just seeking to get along and not violent. There are violent religionists who get a lot of the press and attention, because they seem to demand it. The more moderate voices, both from east and west, do not seem to get the same attention.
So for JW's to sell to a local Muslim group in Connecticut does not mean they're necessarily aiding a terrorist cell. Most likely the people are quite moderate. If you look back to World War 2 history in America, the Germans who spoke their native language here in Minnesota had their loyalty called into question, needlessly so. They were American. At the same time, American citizens of Japanese descent were herded into camps in California, because again it was feared their sympathies lay with Japan. That proved to be untrue. I believe it's similar for moderate Muslims who happen to live in America now. They came here because they like it, and most of them consider themselves American. Of course there are exceptions to that, and those exceptions are the ones that fear is built around.
Just my $.02.
